Influence of the Use of a Collagen Membrane Placed on the Bone Window after Sinus Floor Augmentation—An Experimental Study in Rabbits
2021
Background: We studied the influence on healing of a resorbable membrane covering the osteotomy site after maxillary sinus grafting, evaluated in different regions of the augmented area. Methods: Maxillary sinus augmentation was performed in 24 New Zealand rabbits. Osteotomy, 4 × 6 mm, were performed bilaterally. A collagenated cortico-cancellous porcine bone was used to fill the elevated region. A collagen membrane was randomly placed over the osteotomy site on one side (MG), and the other side was left uncovered (NMG). The animals were euthanized after 2, 4, and 8 weeks
Invasive maxillary sinus aspergillosis: a case report successfully treated with voriconazole and surgical debridement
2014
Introduction: Invasive aspergillosis of the paranasal sinuses is a rare disease and often misdiagnosed; however, its incidence has seen substancial growth over the past 2 decades. Definitive diagnosis of these lesions is based on histological examination and fungal culture. Case Report: An 81-year-old woman with a history of pain in the left maxillary region is presented. The diagnosis was invasive maxillary aspergillosis in immunocompetent patient, which was successfully treated with voriconazole and surgical debridement. Possible clinical manifestations, diagnostic imaging techniques and treatment used are discussed. Since the introduction of voriconazole, there have been several reports …
Immediate or delayed retrieval of the displaced third molar: A review
2019
Background The displacement of a third molar is a rare occurrence, but it could lead to serious and/or life threatening complication. Aim of this review is to understand the most correlated causes of displacement and the possible solutions proposed in literature to avoid and solve this complication for maxillary and mandibular third molars at the appropriate time. Material and methods A search for "third molar displacement" was performed by using Pubmed database. Articles referred to soft tissues displacement, from 1957 to 2018, were included in the review. The references lists of all eligible articles were examined and additional studies were added to the review only if indexed on Pubmed. …
Endoscopic treatment of ectopic teeth in the maxillary sinus.
2020
Background Ectopic teeth in maxillary sinus is rare and are usually removed via sub-labial trans-canine fossa approach (SLCFA). The aim of our study was to present our experience with extraction of ectopic teeth in the maxillary sinus via transnasal endoscopic approach (TEA). Material and methods Rhinologists were asked to share their experience in the management of ectopic teeth in the maxillary sinus. Data were reviewed retrospectively. Results Eleven cases were reported in 10 patients from 2010 to 2019, six males and four females with a mean age of 33.5 +/-17 years (range 16 to 61). Seven patients complained of sinonasal symptoms, two were diagnosed incidentally during routine dental wor…
Clinical and Radiological Long-Term Outcome of a Tapered Implant System with Special Emphasis on the Influence of Augmentation Procedures
2015
Background and Purpose: Tapered implant designs aim to improve primary stability and implant survival in soft bone. However, respective clinical long-term data are scarce. Therefore, a clinical and radiological evaluation of the long-term success of a transgingival-supracrestal inserted tapered implant system with special emphasis on the influence of augmentation procedures was conducted. Material and Methods: In a retrospective study design, all in the Department of Oral and Maxillofacial Surgery of the University Medical Centre, Mainz, Germany, between May 2002 and March 2012, placed tapered implants (Straumann TE®, Basel, Switzerland) were analyzed. In this time period, a total of one hu…
Canine fossa puncture in endoscopic sinus surgery: report of two cases
2017
Abstract Introduction Chronic rhinosinusitis with nasal polyposis is a common chronic disease that often affects maxillary sinus. Endoscopic sinus surgery is the most common procedure for treating the majority of maxillary sinus lesions. Objective To demonstrate the role of canine fossa puncture during endoscopic sinus surgery procedure in patients with severe maxillary sinus disease. Methods We present 2 cases where canine fossa puncture has been performed as method to obtain a complete access to the maxillary antrum. Results According our experience, 2 cases on 296 endoscopic sinus surgery (0.6%) where antrostomy and used of angled microdebrider were not sufficient, canine fossa puncture …
Histological evaluation of maxillary sinus floor augmentation with recombinant human growth and differentiation factor-5-coated β-tricalcium phosphat…

Stavropoulos A, Becker J, Capsius B, Acil Y, Wagner W, Terheyden H: Histological evaluation of maxillary sinus floor augmentation with recombinant human growth and differentiation factor-5-coated β-tricalcium phosphate: results of a multicenter randomized clinical trial. J Clin Periodontol 2011; 38: 966–974. doi: 10.1111/j.1600-051X.2011.01754.x. Abstract Objectives: The aim of this prospective, multicenter, randomized clinical trial was to evaluate histologically the outcome of maxillary sinus lift augmentation with a recombinant human growth and differentiation factor-5-coated β-tricalcium phosphate (rhGDF-5/β-TCP) or with a β-TCP and autogenous bone (β-TCP/AB) composite. Material and Met…
Fungal infections involving maxillary sinus: a difficult diagnostic task
2011
Fungal infections of the paranasal sinus are increasingly recognized entity both in normal and immunocompromised individuals. Aspergillosis and Mucormycoses being the commonest of all the fungal infections involving maxillary sinus manifests as two distinct entities, a non-invasive and invasive infection. It is important to distinguish the invasive disease from the non-invasive as the treatment and prognosis are different in each. These infections present a diagnostic and therapeutic challenge to the physicians. Early diagnosis is essential in order to avoid high morbidity and mortality associated with the destructive disease and to instigate treatment before irreversible condition arise. T…
Removal of fungal ball from the jaws by lefort i osteotomy: Difficulty in diagnosing patients with chronic sinusitis
2021
Aspergillosis, aka fungal ball (FB), is classified as a type of non-invasive fungal rhinosinusitis, which usually occurs unilaterally in the maxillary sinus of an immunocompromised patient. Its diagnosis is complex and depends on the association between clinical, imaging, and histopathological exams. There are many treatments for fungal infections of the paranasal sinuses, so early diagnosis is extremely important to determine the appropriate treatment. This paper reports an unusual clinical case of aspergillosis present bilaterally inside the maxillary sinuses of a healthy patient, associated with mucous retention cysts, whose imaging exams and transnasal endoscopy were not sufficient to p…
Gossypiboma in the oral region: case report and literature review
2014
Gossypiboma is an inflammatory reaction to a foreign body, specifically composed of a cotton matrix left behind after surgery. The present study aims to present a case report of gossypiboma 23 years after a dental surgery and to make a literature review of the English language cases published on the issue. A 42-year-old woman was attended to evaluate complaints of pain on the right side of the maxilla. The patient reported that dental extractions in this region had been performed over a period of nearly 23 years. The panoramic radiograph demonstrated an opacity in the right maxillary sinus, which presented a spongiform aspect, irregularly shaped radiopaque image, as well as a rupture of the…
